I have 5 iPads. Using them to control a home automation system. What is the easiest way to distribute a help doc (PDF) to each of the iPads. I started to check into using iCloud but my MacBook Pro is running 1.6.8. SInce I am not an Apple savant, I thought I would ask the community.... I have a 20MB PDF that I want to distribute to 5 or more iPads over our wireless network.
